Why Berkeley Homes Are Different

Berkeley housing stock runs older than most Bay Area cities. The flatlands between San Pablo Avenue and Shattuck are dense with 1910s and 1920s Craftsman homes, many with original single-pane wood sashes that have warped, rattled, or painted themselves shut over the decades. The hills above Euclid and Grizzly Peak see full afternoon sun on the west slope, which bakes exterior finishes and causes wood frames to expand and contract through wild temperature swings. Then the fog rolls in from the Golden Gate and everything cools fast. That cycle is harder on window and door materials than almost anything else a house endures.

Terrain matters too. Hillside lots in the Berkeley Hills often have homes on raised foundations with noticeable settling, which means existing openings are rarely square. We regularly see gaps of a quarter inch or more between the old frame and the rough opening, which affects how replacement windows are fitted and flashed. Down in the flats, the bigger concerns are moisture and wood rot near the bay side, where morning condensation and decades of coastal air have worked on sills and door thresholds. Berkeley also has strict planning and building rules in certain historic districts, so if you live in a designated landmark area, the city may require review before exterior changes. We help homeowners figure out what applies to their street, not just their house.

Our Main Berkeley Services

Berkeley homeowners call us most about two things: replacing old windows that leak air and make rooms uncomfortable, and swapping out doors that no longer seal or latch properly. Each service has its own page with local pricing and details.

Window Replacement in Berkeley

Most replacement work in Berkeley involves pulling old wood sashes or failing aluminum frames and installing modern units sized to the existing openings. The goal is usually better insulation and easier operation without changing the look of the house, which matters on older Berkeley homes where window proportions are part of the character. On hillside exposures, we recommend glass packages built for solar heat gain and wind exposure. Flatland homes near the bay often benefit from better seals and low-E coatings to manage condensation. Window Replacement in Berkeley covers the full scope, including what different frame materials cost per opening.

Window Installation in Berkeley

New-construction and addition projects in Berkeley call for a different approach than replacement, because installers work with open rough openings before siding and trim go on. In the hills, that often means coordinating with a general contractor on flashing details for sloped sites, while flatland projects may involve seismic anchoring requirements for larger window banks. We’re the installation crew for the windows and doors only, and we show up when the framing is ready. Window Installation in Berkeley explains how we schedule around other trades and what install pricing looks like per unit.

Door Replacement in Berkeley

Front doors in Berkeley take a beating from sun, fog, and uneven settling. A door that sticks in July may swing clear in November once humidity changes, which is why we measure in place rather than relying on nominal sizes. Fiberglass and steel entry doors hold up well against coastal moisture, and many Berkeley homeowners also replace weathered back and side doors with pre-hung units that include fresh framing and weatherstripping. Door Replacement in Berkeley breaks down typical costs for entry doors, patio sliders, and pre-hung replacements.

Brands We Service in Berkeley

We service and install windows and doors from PGT, CGI, CWS, and ES Windows, along with other product lines in our catalog. Because Berkeley jobs range from historic bungalows to modern hillside builds, having access to multiple product lines means the right glass package and frame style for the house, not whatever is left in a warehouse. See our brands for the full list and what each line does best.
